  2. Agenda • About Phoenix Integration • STK / Analyzer • Trade space exploration tools for STK • ModelCenter • Multi-disciplinary analysis and trades

  3. Phoenix Integration: Company Mission Help customers in the aerospace, defense, and related industries fully realize the value of modeling and simulation tools Explore more design alternatives Make better design decisions Reduce time to market Concept Identification Conceptual Design Preliminary Design Detailed Design

  4. Value Proposition Automation Wrap simulation tasks into repeatable actions Integration Chain together multiple wrappers to form end to end simulation workflows Design Exploration (STK/Analyzer) Find better designs Data Management (AGI Data Federate) Data pedigree Infrastructure for enablingSimulation Driven Design

  6. STK/Analyzer Overview • What is it? • A trade study engine for STK • Sample Problems • What is the appropriate orbit to achieve my coverage goals • When is the best launch time to minimize my fuel requirement? • Where should I place my ground stations to achieve highest signal quality • Customer Pain Points • Changing values in STK is a trial and error process • Time consuming • Error prone

  7. STK/Analyzer Trades How does coverage change with inclination angle? How does coverage change when inclination and semi-major are both changed? A launch vehicle will give a certain set of drop-off conditions with known distributions. How does this affect the final orbit? What is the best position to minimize fuel for a maneuver?

  8. New Release: STK/Analyzer 9.2 • Improve ease of use to address the needs of a 2nd wave of users • Minimize scripting/macro requirements • Access all data providers out of the box • Provide complete Object Model coverage • Improve performance • Avoid importing the whole Scenario each time Analyzer loads • Tighter integration with the STK GUI • Eliminate HTML interface, utilize toolbars

  9. New Analyzer GUI Analyzer now launches from a toolbar. To get started, click on the Analyzer icon

  10. Analyzer: Select Variables Instead of importing the whole scenario each time Analyzer loads, users can now just select the variables of interest. This results in significant performance improvements for large scenarios. After selecting an object in the tree, all potential variables for that object are displayed. Variables can be created from any Data Provider.

  11. Results

  12. Other Updates • Time/Date variable types • Multiple accesses as variables • New parameters • Satellite: Mass values • Propagators: HPOP force model • Sensors: Refraction • Transmitter/Receiver: Antenna, Gains & Losses, Filter values • Antenna Objects • Astrogator: Auto Sequence, additional parameters • Intelligent Propagation: only propagate objects that have changed

  13. Network Multi-Disciplinary Analysis Using ModelCenter ModelCenter - Integrated Applications Available Over the Network Components System Results ModelCenter

  14. Evaluating Concepts Run Matrix Design of Experiments Data Collection Data Explorer ModelCenter AoA: Analysis of Alternatives CAIV: Cost As an Independent Variable SoS: Systems of Systems DFSS: Design for Six Sigma MDO: Multi-Disciplinary Optimization

  15. Questions and Answers Grant Soremekun grant@phoenix-int.com 540-808-5812

  16. Time/Date Variables Date variables can now be displayed as string values instead of Epoc seconds

  17. Things to Know • This is a complete rewrite. Older Analyzer setups cannot be loaded into the new Analyzer (saved Trade Studies can still be viewed though) • The new architecture has room to grow. As content is added to the Object Model, we can quickly add content to Analyzer too
